Abstract
Ensuring the dryness of Rice Granules is essential for the storage of Rice. The moisture
content present in the rice granules deteriorates the quality and toughness that is
expected from the the final produce. Existing systems that were put forth to find the
moisture content of rice granules are not efficient enough. Their throughput is
influenced by a variety of factors such as material density and packing.The official oven
method consumes more time .The moisture content present in the rice granules is
calculated using the equilibrium relative humidity technique [ERH]. The equilibrium
relative humidity, and temperature, of rice granules were measured by using
temperature and relative humidity sensors. Sensors are calibrated to improve
accurateness and precision. The moisture content was calculated by using an
equilibrium moisture content model. The data collected from the sensors are sent to the
user which gives intimation about the prevailing conditions in the storage place as a
message. According to the message, the prevention methods are listed. The error of the
moisture content determined with this method was within 0.5% w.b. at moisture.

Abstract
Microalgae have long been considered as a promising feedstock for biomass production.
The annual world production of microalgal biomass in 2007 was estimated of about
5000–7500 ton, generating average annual income of US$ 1.25 billion. The present study
aimed to evaluate the climate key parameters for Scenedesmus obliquus outdoor
biomass production during all seasons. Scenedesmus obliquus was grown continuously
in municipal wastewater using tubular photobioreactors (PBR) made of plastic sleeves
arranged vertically in a pilot area of 6 m2 with a total working volume of ≈850 L.
Biomass productivity showed positive correlation with light intensity and temperature
(0.824 and 0.697, respectively). On the other hand, a negative correlation was recorded
between biomass productivity and rainfall (-0.520). The average biomass productivity
increased directly with the light intensity/temperature from 10 to 23 g dry weight (DW)
m-2 d-1 for a low light/temperature of 4 MJ m-2/4 ºC and high light/temperature of 22
MJ m-2/21 ºC, respectively. At high rainfall of 58 mm d-1, the biomass productivity was
reduced to 9 g DW m-2 d-1. The productivity ranged during all seasons from 8.5 up to
22.9 g DW m-2 d-1 with a mean productivity of 17.9±3.9 g DW m-2 d-1. Although the
used system showed high efficiency for algae cultivation, high light fluctuation in
Shenzhen climate requires continuous regulation of the biomass concentration in PBR
for optimization of outdoor microalgal production systems.

Abstract
The Majority of Cameroonian living in the rural areas depend on agriculture for their
sustainable livelihood. Many have no access to electricity and they use firewood as their
major source of energy for cooking. This situation is not sustainable and also has a
negative impact on the environment. The biogas digester is not only a cost effective
solution to address these concerns but also presents less negative impact to the
environment. It is with is in mind that we have developed a biogas digester that is a
simple, yet powerful sanitation technology option that is capable of: (i) processing
human and animal feces into safe and free fertilizer; (ii) reducing cases of groundwater
contamination by processing feces instead of having it discharged untreated; (iii)
creating biogas for use in cooking and household lighting; (iv) empowering women and
families by reducing their time spent on gathering fuel wood and cooking; (v) reducing
indoor air pollution brought about by burning fuel wood; and (vi) eliminating carbon
dioxide (CO2) and methane (CH4) emissions during fermentation of openly-discharged
sewage, thereby helping to reduce the threat of climate change. We therefore present
this simple technology that has the potential of transforming lives especially in rural
areas.

Abstract
Dye-sensitized solar cells (DSSCs) have been considered as a promising alternative to
conventional silicon-based solar cells due to their low production cost, simple fabrication
process, and high efficiency. However, the highest power conversion efficiency reported
for DSSCs to date is only 13%, which is far lower than the conventional solar cells
(25.6%). In this study, aluminium-based metal-organic framework Al-BDC and reduced
graphene oxide were incorporated into photoanode to improve the overall photovoltaic
performance of DSSCs. The Al-BDC was incorporated into TiO2 photoanode to
suppress the charge recombination between TiO2 and electrolyte. The large specific
surface area of Al-BDC could enhance the dye adsorption on TiO2 layer and thus
improve the power conversion efficiency of the cell. In addition, Al-BDC could be
incorporated as light-scattering layer in DSSC to improve the optical absorption of the
incident light. It was fabricated onto TiO2 through layer-by-layer (LbL) assembly.
FTO/TiO2 interface is another common recombination centre for charge carriers in
DSSC. To tackle this problem, reduced graphene oxide was incorporated as compact
layer to improve the contact between FTO and TiO2 and prevent recombination
between the FTO and electrolyte solution. This study provides a new insight into the
fabrication of photoanode of high performance DSSC devices. It is expected that DSSCs
assembled from these combinations could exhibit higher power conversion efficiency
compared to Al-BDC and TiO2 alone.

functionalization of MIL-125 (NH₂-MIL-125) is able to narrow the energy band gap to
2.6 eV. Both MIL-125 and NH₂-MIL-125 were synthesized through reflux method and
used as a catalyst for methylene blue (MB) removal. Preliminary result shows that NH₂MIL-125 has better photocatalytic efficiency compare to MIL-125. Through this work,
we also found that photocatalytic efficiency of NH₂-MIL-125 can be further improved
by doping silver ion (Ag⁺) and incorporating of graphene oxide (GO) into the
framework, or addition of H2O2 into reaction solution.

Abstract
The use of nanoparticles in sensing is attracting the interest of many researchers. The
aim of the present work was to fabricate Acacia gum-stabilised silver nanoparticles
(SNPs) using green chemistry in order to use them as a highly sensitive and cost-effective
localised surface plasmon resonance colorimeter sensor for the determination of reactive
oxygen species that was hydrogen peroxide. In this study, SNPs were fabricated by
reduction of an inorganic precursor silver nitrate solution using white sugar as the
reducing reagent and Acacia gum as the stabilising reagent and a sonication bath to
form uniform silver nanoparticles. Plasmon colorimetric sensing of H2O2 solution was
investigated by introducing H2O2 solution into Acacia gum-capped SNPs dispersion,
and the change in the LSPR band in the UV-Vis region of spectra was monitored. In the
present study, it was found that the yellow colour of Acacia gum-stabilised SNPs
gradually changed to transparent, and moreover, a remarkable change in the LSPR
absorbance strength was observed. The calibration curve was linear over 0.1–0.000001
M of H2O2 with a correlation estimation of 0.9527. This was due to the aggregation of
SNPs following introduction of the H2O2 solution. Furthermore, the fabricated SNPs
were successfully utilised to detect H2O2 solution in a liquid milk sample, thereby
demonstrating the ability of the fabricated SNPs to detect H2O2 solution in liquid milk
samples. This work showed that Acacia gum-stabilised SNPs may have potential for
medical and environmental applications as a colour indicator.

Abstract
ZIF-67 is a nanoporous metal-organic compound with sodalite framework topology.
ZIF-67 is an effective adsorbent for the removal of some organic pollutants, such as
Malachite Green (MG) and Acid Blue 40 (AB40) in water. It also an efficient catalyst in
the synthesis of ethyl methyl carbonate. However, adsorption capacity and
photocatalytic activity of the modified ZIF-6 remains unclear. Here, we present the
adsorption and photocatalytic activity of the GO-supported ZIF-67 (ZIF-67@GO)
synthesized by mixing ZIF-67 precursors to certain portion of GO in water. The
synthesized ZIF-67@GO showed exceptional adsorption ability towards both anionic
Methyl Orange (MO) and cationic Methylene Blue (MB). ZIF-67@GO also significant
for degrading MO and MB under visible radiation with an optimum photocatalytic
activity at neutral pH. This implies that small amount of GO can significantly alter the
surface morphology of ZIF-67 which makes ZIF-67@GO material an effective
adsorbent and photocatalyst regardless to the types of pollutant.

Abstract
The actual energy demand, food-versus-fuel conflict and environmental concerns
together with replacing the current fossil fuel resources have much public attention to
converting the second generation bioethanol into an attractive research goal. The
present study aimed to screen a novel yeast species from the gut symbionts of woodfeeding termite as well as to evaluate its tolerance for multiple types of stress conditions
associated with second-generation ethanol production for the future biomass industrial
application. During a yeast screening from wood-feeding termites in China, a novel
strain of basidiomycetous yeast species was isolated from the lower termite gut
Reticulitermes chinesis (Snyder) collected from WuHan in HuBei Province, Hauzhong
Agricultural University, China. The morphological, physiological, biochemical and DNA
sequencing characteristics were examined according to standard methods that are
employed in yeast taxonomy and it was identified as a novel species in the genus
Rhodotorula. The name Rhodotorula lignophila sp. nov. is proposed to accommodate
this strain. The type strain is KU513951T (= CBS 7109T ). In order to screen a novel
yeast with potential growth properties in the presence of various stresses as a promising
strain to serve as a platform for bioethanol production, many stresses were conducted. It
has been reported as potent cellulase and xylanase producing isolate. Pre-treatment of

lignocellulosic biomass release C6 (glucose, mannose and galactose) and C5 (arabinose
and xylose) sugars. The growth results of the tested strain on various sugars (100 g/l)
showed that the sucrose was the most preferred sugar. It showed good growth on
glucose, galactose, maltose, and xylose, whereas the strain was failed to grow on
mannose and arabinose. The production of toxic compounds during the pre-treatment
adversely affects not only the yeast cell growth but also fermentation capabilities. Novel
yeast strains with increased tolerance to furfural would make lignocellulosic ethanol
production cost-effective. In this concern, KU513951T displayed higher growth at 1.0 g/l
furfural. On the other hand, high temperature and high initial ethanol concentration are
potent inhibitors on the fermentation performance of yeast strains. Therefore, the
investigated strain displayed higher growth when the cells were spotted on YEPD plates
containing 10 % ethanol and at 45°C. The use of novel salt-tolerant yeast is of industrial
importance for bioethanol production that reduces desalting costs and decreases the
possibility of contamination. The results showed that the tested strain displayed higher
growth on YPGS plates containing 70 g/l Na2SO4. In conclusion, the present study will
be beneficial for selection of natural novel yeast strains with multiple stress-tolerant
properties for future lignocellulosic bioethanol production under high-stress conditions.

Abstract
Chromium is a toxic heavy metal used in industries such as tannery, alloy preparation
and electroplating. Direct discharge of chromium retentive effluents from these
industries can contaminate the environment and cause chronic diseases as well as
mutations, birth defects and cancers in human being. Hence, it is important to remove
Cr(III) from the contaminated environment. In this study, a polymer layer silicate
composite was developed, using kaolin (a layered silicate) and alginate (a biopolymer
from seaweeds) to enhance the adsorption capacity of each material.Sodium alginate (A)
was dissolved in 100 mL distilled water at 80 °C for 3 h. Thereafter, thoroughly cleaned
kaolin (K) was added to the solution (A:K=1:20) and stirred for 5 h and the mixture was

cooled to room temperature. The mixture was then added dropwise to 1% CaCl2
solution. The beads formed were washed with distilled water and dried at 70 ºC for 2
days. The dried composite was ground and sieved to obtain 250 - 350 µm size particles.
All the experiments were conducted using 0.20 g of the composite and 100 mL of 5.0 mg
L-1 except for isotherm study where the concentration of Cr(III) varied from 0.5-30 mg
L-1. Suspensions were shaken on an orbital shaker at a constant speed of 100 rpm. The
effect of pH on adsorption efficiency was determined by varying the initial pH of the
solution.
The dried composite material adsorbed 97% (2.02 g m-1) of the Cr(III) from aqueous
system within 120 min. The pH of the metal solution influenced the adsorption process
where the maximum adsorption of 97% was observed within pH range 4-6. The kinetic
data were fitted to pseudo first order and pseudo second order kinetic model.
Adsorption system followed pseudo second order kinetic model with a rate constant of
0.03276 g mg-1 min-1. The Langmuir isotherm model was found to fit the isotherm data
with a monolayer capacity of 6.14 mg g-1 and a RL value of 0.05-0.65. The adsorption is
a homogeneous adsorption process, which forms a monolayer of Cr(III) on the
adsorbent surface. This study indicates that the kaolin:alginate composite could be used
as a cost-effective and environmentally friendly green adsorbent to remove Cr(III) from
contaminated aqueous environments. Financial assistance from National Research
Council- (Grant No13-087) is acknowledged.

Abstract
Phosphates are widely used in water- based paints, plastics, cleaning solutions and
fertilizers. Phosphate enters the water body as human and animal waste, industrial
effluents, and mainly fertilizer run-off. At low concentration, phosphates are not toxic
to human health. However, it can stimulate the growth of aquatic plants and algae
leading to eutrophication. In this study removal of phosphate from aqueous system was
investigated using a composite material prepared by sol-gel method using agar, alginate
and feldspar.
Feldspar (20 g) was added to an agar solution (10%) in water and the mixture was
stirred for 2 h. A freshly prepared solution of sodium alginate (2.5%) in water was
added to the mixture of agar and feldspar and the resultant mixture was stirred for 6 h.
Thereafter mixture was added drop- wise to a mixture of 3% Ca2+ and 0.5 % Fe3+
solutions. The beads formed were allowed to stand for 48 h to complete solidification.
The beads were filtered and washed with distilled water until the filtrate was neutral.
Synthetic phosphate stock solution was used for all the experiments and the residual
phosphate concentration was determined using UV-Vis spectrophotometer by Ascorbic
acid method. The kinetic study was conducted with the adsorbent dosage of 20.0 g L-1
and 25.0 mL of 5.0 mg L-1 phosphate solution at pH 6.5 at 27 ºC and the data were fitted
to kinetic models. The adsorption was further studied with varying initial pH values (i.e.
pH 1.0 – pH 12.0) and a series of initial phosphate concentrations (i.e. 1.0 – 50.0 mg L-1).
The adsorption data were fitted to isotherm models.
In this study, the equilibrium time was found to be 570 min and the maximum
phosphate adsorption was 81.0%. The adsorption process followed pseudo 2nd order
kinetic model with the rate constant of 0.10 L mg-1 min -1. The optimum pH for the
adsorption process was pH 8 with 91.0% adsorption. Adsorption isotherm data fitted
the Sips isotherm model with a high R2. This study indicates that feldspar-agar-alginate
composite can be used as environmentally- friendly adsorbent to remove phosphate

Abstract
In this study, a novel cost-effective eco-friendly sorbent was developed from a
lignocellulosic agro-food-waste abundantly available in Malaysia (Artocarpus Integer
peel waste) through a total ecologically benign production route. The sorbent
preparation parameters were optimized and the optimal sorbent was characterized by
N2 adsorption-desorption, FTIR, XPS, FESEM, TEM, XRD, EDX, TGA and DSC
instrumental analyses. This newly produced sorbent was evaluated for the removal of
carcinogenic chloroethylenes (tetra-, tri- and dichloroethylene) from polluted water. The
effects of sorbent dosage, pH, temperature, initial concentration of chloroethylenes and
agitation time on removal of chloroethylenes were examined by GC-MS. Our findings
indicated that the produced sorbent is highly micro-mesoporous (BET surface area ~853
m2 g-1, t-plot micropore surface area ~506 m2 g-1, t-plot mesopore surface area ~346 m2 g1
and average pore width 2.9 nm) with amorphous nature and mainly basic surface
functional groups, which are all beneficial features for adsorption applications. EDX
spectra revealed the presence of chloride peak and elemental mapping analysis showed a
high distribution of chlorine in the sorbent after sorption experiments, proving that the
sorbent is capable of effectively extracting chloroethylenes from contaminated water.
The maximum removal of tetra-, tri- and dichloroethylene was obtained at pH 8 as 87
%, 85% and 82% respectively for bio-sorbent dose of 5 g L-1 and 50 mg L-1 initial
chloroethylene concentration at 40 °C. This judicious transformation of agro-food-waste
not only addresses the disposal issue, but also generates value-added functional material
from the discard, which will be highly beneficial for low- and middle-income countries.
Widening the applicability of the novel eco-friendly sorbent will be the platform of our
future investigations.

Abstract
Building of the nanoparticle form their precursors by bottom-up method is a very
fascinating practice in nanotechnology. Most promising two bottom-up methods are
experimentally unveiled in this research contribution; i) controlled precipitation of Ni
nanoparticles and their reinforcement with silicate by modified Stöber method and ii)
chemical vapor deposition of nano-carbon from methane over silicate supported nano-Ni
catalyst. We found that the silicate addition results in the formation of single crystal NiO
nanoparticles which exhibited catalytic activity enhancing features, such as low particle
size and high surface area and porosity. The single-point surface area was increased
from 62.22 m2/g to 91.50 m2/g for n-NiO nanoparticles, after silicate incorporation.
Preliminary catalytic activity was also analyzed in a fixed-bed pilot plant. n-NiO/SiO2
nanoparticles generated 57.28% hydrogen at 730 °C. Isothermal methane decomposition

ABSTRACT
Natural ventilation is considered as one of the most fundamental low cost passive cooling
strategies. A major part of building potential in terms of using natural energy resources
such as wind depends on its physical characteristics, so architectural decisions at the
first step of design process can influence the buildings energy efficiency significantly.
Courtyards are just one of the numerous passive cooling strategies in ancient buildings
that are currently enjoying great popularity. However various configurations of these
components will influence their efficiency in terms of receiving natural ventilation.
The main objective of this paper was to investigate the influence of courtyard
proportions on their natural ventilation efficiency and to introduce the most effective
features in this field. The outcome of these researches could be used as a guideline for
architects at the first steps of design process.
Investigations indicated that reducing the length of windward side would result in better
airflow pattern both inside the courtyard and interior space of a building. So it is
suggested to design a courtyard with elongation in the wind direction and minimum
windward side length to receive maximum airflow rate and take advantage of natural
ventilation.
Keywords: Wind, Natural Ventilation, Architecture, Courtyard.

Abstract
The paper attempts to investigate the risk types in Fadama farming, as well as the
strategies for risk management utilized by Fadama farmers in Jigawa state. Over 75%
of the state landmass is considered arable which make it one of the most agriculturally
endowed states in Nigeria. However, the area is confronted by multiple natural,
ecological, social and economic problems. This research focus mainly on the challenges
and prospects of Fadama agricultural production as well as rural livelihood in the area
under study. Three null hypotheses were formulated, and tested at 0.05 level of
significance. The sample comprised of 150 professional farmers selected from the total
population of 350 through simple random sampling procedure. The instrument used in
the research was the self assessment questionnaire (SAQ) developed by the researcher.
The data collected were analyzed using rank ordered. The findings revealed that, the
major risk encountered by Fadama farmers are market related, natural/social and
whether related risks. Market related risk constitutes the major peril to Fadama
farming with glut as its major features. The strategies for managing risk by Fadama
farmers essentially help to minimize probable looses from current production or to
manage the consequences of inevitable losses.
Keywords—fadama farming, management, irrigation and risk analysis.

degrading isolates were isolated. These isolates were characterized by two tests of
degradation and by restriction fragment length polymorphism (RFLP) analysis of 16S
rDNA genes amplified by PCR.
Based on the sequences of 16S rDNA genes obtained and by comparison to databases,
isolates were grouped in four microbial
groups:
Achromobacter
xylosoxidans,
Cupriavidus respiraculi, Ralstonia sp and beta-proteobacterium.
The compilation of these results with results of the 24-well microplate mineralization
procedure helped to identify 2,4-D degrading bacterial populations which can be used
for 2,4-D bioremediation.
To propose solutions allowing to limit the resistance time of pesticides in the studied
soils, inoculation of 49MC soil with one of this isolates adapted to the degradation of 2,4D (bioremediation test) led to a significant increase in the degradation rate of this
herbicide.

Abstract
Masao River, located in Agusan del Norte, Mindanao, Philippines is home to many
organisms especially those associated with the freshwater communities. Fishes were
abundantly present including one of the commercially important fishes, the Ambassis
interupta, locally known as “ibis”. This study describes the variations in body shapes
of A. interupta using landmark-based geometric morphometric analysis. A total of
100 fish samples, collected from Masao River were digitized using sixteen landmark
points. The Procrustes ANOVA showed differences in the patterns of asymmetry
between sexes of the fishes. Three factors were analyzed for fluctuating asymmetry
(FA) and these were: individuals, sides, and interaction of individuals and sides. The
individual symmetry among the fish samples showed no significant differences, while
the sides and interaction of individuals and sides showed a highly significant
difference (P<0.0001). The results implied asymmetry in the left and right side of each
sample, also in the interaction of individuals and sides. However, the individuals were
symmetrical with each other. Principal Component Analysis revealed that the five
significant principal components (PC1-PC5) contribute most to the variation that
exist among individuals. A total of 71.46% of the variation exist in the FA interaction
in female fish and a total of 62.04% is observed in the FA interaction in male fish.
The results however indicate that fluctuating asymmetry are higher compared to
individual variation in females, but individual variation is higher compared to
fluctuating asymmetry in males.

Abstract
Fluctuating asymmetry has widely used as an indicator of an ecological stress of an
organism’s population. Stress can increase the phenotypic difference in a population
thereby affecting the stability of an individual. Thus, increased in stress may result to
the asymmetry of each bilateral traits, especially during development. In this study,
Mugil cephalus was used because this fish is capable in surviving brackish, salt, and
freshwater environments. Thin plate spline (TPS) series was used for landmark
analyses of each sample and were subjected to Symmetry and Asymmetry in
Geometric Data (SAGE) software. Results of the Procrustes ANOVA showed that
individual symmetry of L-R sides presented in males were not significant. However, in
females the individual symmetry were not statistically significant. The results of
Principal Component (PC) scores presents high percentage FA of male (73.9541%)
and female (82.6848%), respectively. In males, all the principal components has its
fluctuating asymmetry which means that there is a difference in the samples body
shape which it has its affected landmarks. In females, their FA gives a hint that there
is a difference between the individuals’ body shape. Wherein the highest percentile
was in PC1 which means that all landmarks are affected. This study aimed to
determine the fluctuating asymmetry in the body shapes of M. cephalus as an
indicator of the water quality of Masao River, Butuan City, Philippines.

Abstract
Selection for drought tolerance of fifteen wheat genotypes (five parents and their ten
F1 hybrids) was performed under laboratory .Three different callus induction media
were used to determine the optimum hormone balance for callus induction from
mature embryos of wheat genotypes and also to study the genetic response of the
studied wheat genotypes to callus induction. MS media supplemented with different
concentrations of poly ethylene glycol (PEG) were used to evaluate the obtained calli
for drought tolerance. Then the drought stressed calli were then transferred to plant
regeneration medium for studying their ability to regenerate.
M2 medium (2mg/l 2,4D+300 mg/l casein hydrolysate) gave the highest callus
induction frequency (85.5%) followed by M1 (2mg/l 2,4D) medium (85%) and M3
(2mg/l 2,4D +4 mg/l AgNo3) medium (81.6%). The differences between the three
callus induction media were significant for all characters except callus induction
frequency (CIF %) and M2 medium was the best media for callus induction.
Regeneration was obtained in all genotypes under 0, 5 and 10% PEG, and in most
genotypes under 15% PEG, but was completely absent under 20% PEG.
Data obtained revealed that the parental cultivars, Giza168 and Sids13 and their
hybrid (Giza168 xSids13) were the most drought tolerant
genotypes, while the
parent Misr1 was the most sensitive to drought.
A set of ISSR markers for drought tolerance and (BSA) approach were used in
molecular studies. Five tolerant molecular markers appeared in positive molecular
markers for drought tolerance.

perform a wide range of functions. TA systems are more prevalent in pathogenic
bacteria as compared to their non-pathogenic counterparts. Salmonella has been
reported to contain several type I and type II TA system. The hemolysin expression
modulating protein Hha and its adjacent protein TomB (previously known as YbaJ)
have been proposed to form TA module in E. coli. However, in Salmonella this TA
system is not characterized. In this study, the Hha-TomB TA system from S.
Typhimurium was characterized in detail and their role in various cellular processes
were elucidated. The described study found that Hha and TomB pair bears all the
characteristic features of a bonafide type II TA system. This TA system was found to
play an important role in bacterial persistence against antibiotics. Furthermore, the
TA system repressed biofilm formation. Interestingly, the toxin components i.e. Hha
showed conditional toxicity and was found to cause cell death under acid stress. On
the other hand, itscounterpart, i.e. TomB provided survival fitness to S. Typhimurium
under acid stress conditions. In addition, Hha-TomB TA locus was also found to be
present on a plasmid; however, the function of plasmid copy of this TA system still
remains to be elucidated.

Abstract
To handle a large scale administrative control of data security in cloud, a new hybrid
encryption based cloud intrusion detection system model has been proposed in this
paper. Our proposed cloud Intrusion Detection System (IDS) handles large flow of
data packets, analyse them and generate alerts by integrating knowledge and
behavior analysis to detect intrusions. Differential Fault Analysis (DFA) attacks on
Advanced Encryption Standard (AES) key schedule has been used to generate
encryption keys for data security in end to end transmission. The security algorithms
used for encrypted/decrypted data are essential for cloud computing, which will
maintain the confidentiality of the data. In addition fuzzy based rule generation are to
detect attacks and protect data/ application in cloud. Performance of this cloud IDS
system is evaluated for various sizes of text files, on the basis of encryption/decryption
processing time and memory. The cloud IDS security levels has also been analysed
and compared with other existing encryption techniques.

Abstract
Two oils were separated using Thin Layer Chromatography (TLC) and initial
characterisation of the aliphatic and aromatic fraction was carried out by GC and
GC/MS analysis. Asphaltenes from the crude oil were then extracted and subjected to
ruthenium ion catalysed oxidation (RICO) in order to investigate the hydrocarbon
and biomarkers occluded onto the asphaltenes. The asphaltene-bound hydrocarbons
were compared with the maltene-derived hydrocarbon to evaluate the effect of
biodegradation on asphaltene-bound biomarkers. The biodegraded maltene-derived
hydrocarbons show depletion of n-alkanes, acyclic isoprenoids and alteration to
sterane and hopane biomarkers. However, asphaltene-bound hydrocarbon shows nalkanoic acid distribution from C7 – C34 which corresponds to n-alkanes suggesting
protection of the hydrocarbons from biodegradation. The steranoic acids of nondegraded sample show similar distribution to corresponding steranes in the maltenes.
This is different for biodegraded samples which have different distribution of
steranoic acids with the steranes counterparts in the maltenes suggesting secondary

similar distribution as compared to their hopane counterparts in maltenes. The
distribution of asphaltene-bound biomarkers is suggested to represent two oil samples
which is protected from biodegradation as a result of being occluded onto asphaltenes.
This result shows the possibility of using asphaltene-bound biomarkers as an
alternative oil-source correlation technique especially in biodegraded oil samples
where the biomarkers from the maltenes fraction have been altered.

Abstract
Two compounds of bis-benzoylthiourea derivatives were synthesized and their
ionophore potential in Pb(II) ion-selective electrodes (ISEs) with self-plasticizing
poly(n-butylacrylate) (poly-nBA) membrane was examined. As ionophores, 1,4bis(N’-benzoylthioureido)benzene (p-BTB) gave the best results in Pb(II) ISE
compared to 1,4-bis(N’-benzoylthioureido)cyclohexane (p-BTCH). The p-BTB based
electrode resulted in Nernstian response (28.38 mV/dec) over a wide concentration
range with low detection limit, while the p-BTCH based ones showed near-Nernstian
responses. The proposed electrodes show good discrimination toward Pb2+ ion with
respect to several selected cations. The p-BTB-based electrode was also successfully
used to determine Pb2+ ions in real samples.
Index Terms— bis-benzoylthiourea, ionophores, poly(n-butylacrylate) membrane,
Pb(II) ion-selective electrode.

Abstract
Microalgae has been on demand for naturally occuring bioactive compounds since the
world facing global challenges such as climate changes, shortage in renewable sources
and increasing populations. The ability of microalgae to survive in a harsh
environment makes them vulnerable and potential new renewable sources. Bioactive
compound such as carotenoids could be one of the alternative renewable sources in
application of functional foods, cosmetic and pharmaceutical industries. Green
unicellular microalgae Chlorella vulgaris once was known as the most exciting
nutritional was used in this study. Chlorella vulgaris produced high amount of lutein
and β-carotene. Lutein, a novel carotenoid and have benefit human in term of its
function in precursor for vitamin A. In this present study, we only investigated
optimization of ultrasonic-assisted extraction of lutein via response surface
methodology. Green extraction technology, ultrasonic-assisted extraction was applied
on lutein due to its ability to enhance the production of carotenoid. The effect of
extraction time (15-155 min), ethanol volume (35-95%, v/v), extraction temperature
(15-75oC) and liquid/solid ratio (30-150 mL/g) of Chlorella vulgaris on lutein was
examined using central composite design. The optimum conditions for lutein
production was: extraction time (81 min), ethanol volume (88%, v/v), extraction
temperature (69oC) and liquid/solid ratio (114 mL/g). A 3D response plot was
constructed to show the interaction effect between the parameters and R2 value
approaching unity indicates the accuracy of the model. The experimental value under
the optimum conditions for lutein was 4.844 mg/g which is very significant showing
that the value are in good consistent with the predicted value. The high production of
lutein showed that Chlorella vulgaris can be considered as a reliable renewable
sources in industrial scale.

Abstract
In continuation of our previously published researches in Fuel Journal, we move
ahead to explored the potential of metal doped mesoporous silica for
hydrodeoxygenation of dibenzofuran to fuel graded molecules. To actualized that,
titanium containing Ti-MCM-41 and MCM-41 as catalysts supports, were synthesized
and their physicochemical properties were examined through XRD, FTIR, UV-VIS,
NH3-TPD, and N2 isothermal adsorption analysis. These support were coimpregnated with Ni(NO3)2.6H2O and Cu(NO3)2.3H2O solutions, dried, calcined
and reduced with H2. Prior to calcination, the dried samples were analysed by TPO
and after calcinations by TPR then further characterized by XRD, Raman, BET,
FESEM and XPS and. The XRD and BET analysis of supports disclose the formation
of hexagonal structures with larger surface area of 983m2/g and 705m2/g and with
smaller pore size distribution in MCM-41 as compared to Ti-MCM-41 support. The
FTIR and UV-Visible spectroscopic analysis described the existence of tetrahedrally
co-ordinated titanium species in the silica matrix which generated strong Lewis sites
and resulted to emanation of weak Bronsted sites as indicated by NH3-TPD. On the
other hand, The Raman and XRD of supported catalysts revealed the existence of
cubic phase of NiO. H2-TPR and XPS results show that, Cu2+ and Ni2+ were
simultaneously reduced to Cu0 and Ni0, to formed bimetallic Cu-Ni alloy. A high
dispersion of Cu-Ni particles were obtained, as evidenced by FESEM studies. The
supported catalysts were tested for hydrodeoxygenations of Dibenzofuran at reaction
temperature of 250oC, hydrogen pressure of 10MPa and 4hrs reaction time. Also the
effect of reaction time from 4hr, 3hr, 2hr and 1hr have been checked. The NiCu/TiMCM-41 proved to be highly active with 95% conversion than NiCu/MCM-41 with

42% conversion and highly selective to bicyclohexane with the yield of 69.60% than
NiCu/MCM-41 with the yield of 8.7%. The Products distribution showed that,
hydrogenolysis pathway predominate over Ti-MCM-41 supported catalysts via
C(SP2)-O cleavage while hydrogenation pathway predominates over MCM-41
supported catalysts via aromaticity lost. According to effect of time, both conversion
and selectivity increase with increase of reaction time.

different universities of Islamabad and the young users of this application provided
good support for the hypotheses. The results indicate that Snapchat usage has a
positive relationship with privacy and procrastination and negative relationship with
academic performance. The positive relation shows I) the more people inclining
towards usage of Snapchat increases their concerns of privacy, we found that
individuals are not sure whether their personal data is safe or not. II) Increased
Snapchat usage increases procrastination. We found out that almost all individuals
use Snapchat before doing any other task. III) The excess use of Snapchat impacts
academic performance negatively. The more people spend time socializing on

Abstract
Inspite of availability of various techniques, software testing has been always a
tedious task in software industry as it consumes more money, time and effort.
Regression testing is one such important phase of testing which ensures that there is
no impact in the functionality of the previously working software segments. For this,
entire set of test cases of already existing program segments along with the test cases
for the modified segment should also be run which consumes more cost and testers’
effort. This problem can be solved by using test case prioritization technique. This
paper gives a deep analysis on test case prioritization techniques and a method has

Adaptive Choices for Parameter of the Dai-Liao Class of Nonlinear Conjugate
Gradient Methods for Unconstrained Optimization

[email protected]
Abstract
For solving large-scale unconstrained optimization problems, methods with the
important feature of low memory requirement are helpful. Specifically, in the case
where the objective function is smooth and analytic expression of its gradient is
available, conjugate gradient (CG) methods are among the most useful techniques
because of strong global convergence properties and simple iterative formula [6,7]. As
known, the methods are iterative in the sense of generating a sequence of successively
better approximations to the solution. In a recent effort to employ quasi-Newton
aspects in the CG methods [8], based on an extended conjugacy condition a oneparameter class of nonlinear CG methods has been proposed by Dai and Liao (DL)
[5]. Although the methods have been shown to be globally convergent and they can be
practically promising [6], their performance is very dependent to the DL parameter
for which there is no any optimal choice [1]. To the best of our knowledge, a constant
choice for the DL parameter may not lead to an appropriate numerical
behavior.Conducting some eigenvalue and singular value analyses, here we discuss
several adaptive choices for the DL parameter. One of them ensures the (sufficient)
descent property [2] which plays an important role in global convergence of the CG
methods. The other choices obtained in a way to decrease some upper bounds of
condition number of the DL search direction matrix [3,4] and so, they may enhance
numerical stability of the DL method. Computational experiments are done using
standard benchmarks; they provide numerical support for our theoretical arguments.

Abstract
This paper presents the application of Taguchi experimental technique and the S/NANOVA analysis approach for optimizing the surface roughness in machining of
fabricated aluminium hybrid metal matrix composite (Al/SiNp/B4Cp) during
continuous turning of composite rods by Poly Crystalline Diamond (PCD 1600 Grade)
inserts. The volume fraction of SiNp is 7% and that of B4Cp is 5%. Machining of
Hybrid MMC’s with good surface finish is very difficult and in open literature survey
proves that PCD inserts are best suited. The experiments have been conducted using
Taguchi’s experimental design technique. The machining parameters used are cutting
speed, feed and depth of cut. The effect of machining parameters on surface
roughness is evaluated and the optimum cutting condition for minimizing the surface
roughness is determined using S/N ratio. Analysis of Variance (ANOVA) technique is
used to find the most influencing machining parameter for surface roughness. It is
concluded that most influencing parameter is feed followed by cutting speed for the
hybrid aluminium metal matrix composite (Al/SiNp/B4Cp).

Abstract
Chicken fat waste pyrolysis using a series of zeolite (ZSM-5, mordenite, ferrierite) was
performed in a laboratory scale of fluidized bed reactor. The pyrolysis process
produced a significant amount of liquid bio-oil with solid bio-char and syn-gas as byproducts. The aim of this research is to produce and characterize bio-oil and bio-char
obtained from pyrolysis of chicken fat waste in the presence of zeolite. The advantage
of using zeolite is the process can be performed under atmospheric pressure with no
hydrogen gas is required. Zeolite can react with pyrolysis bio-oils to reduce the
oxygen content and improve bio-oil thermal stability. The pyrolysis process using
zeolite usually involves the reaction of dehydration, cracking, polymerisation,
deoxygenation and aromatization in the bio-oil. The feed: zeolite ratio and reaction
temperature were varied and different type of zeolites were used. The chemical
analysis using GC-MS and FTIR for spectroscopic analysis demonstrated different
classes of organic compounds and complex mixture such as hydrocarbons (alkanes,
alkenes, cyclic compounds), aldehydes, ketone, esters, carboxylic acids and other
compounds in liquid bio-oil. The presence of zeolite increases the formation of
alkanes, alkenes and carboxylic acids compounds and reduced alcohol compounds.
The spent zeolite can be regenerated for reproducibility of pyrolysis process. Bio-char
produced contain high ash composition and low carbon composition which make
them irrelevant to other chemical application.

Abstract
Today, tourism is one of the most dynamic activities in the socio-economic change in
the area of the world that has increasingly become important. Because Information
technology, cultural, political, social and economic infrastructures that create in the
twenty-first century, tourism is an inevitable phenomenon of human behavior and
action which would satisfy his curiosity spirit. Tourism as one of the sources of income
and job creation at the local level which could be a strategy for economic development
and in other economic sectors, especially at a time when profits are falling attractive
alternative for them and a strategy for development. Sari city is one of the oldest cities
in northern of Iran, which in addition to historically valuable and lively nature has
perfect texture. Because of underdevelopment in recent years, the central part of the
city that features one of traditional cities is included in decline. The subject matter in
present study is evaluating the potential of city tourism in sustainable development.
From the perspective of a problem, an imbalance in space could be expressed toward
intervention in Space. In this article, we describe the precise definition of sustainable
development and its role in the sustainable development of tourism in the Sari city

and in addition to introducing and identifying the capabilities of the Sari city, the
impacts of tourism development on urban development should be considered. In this
view, the development of tourism by using existing resources in such a way that we
respond to the needs of economic, social, cultural and legal norms and expectations of
tourists to the unity of integrity, cultural identity, environmental health, economic
balance and welfare of the people. To achieve this goal, we must promote local
development and improve the quality of life of host; we should promote cultural, local

Microstructures, Interactions and Dynamics Properties Studies of
Nmethyldiethanolamine + Guanidinium Triflate Ionic Liquid + Water Tertiary
System at the Standard Temperature

Abstract
Molecular dynamics simulations with an all-atom force field have been carried out in
order to understand the phase equilibrium behaviour of ternary aqueous mixtures
containing guanidinium triflate ionic liquid [gua][OTf] and water mixed with Nmethyldiethanolamine (MDEA) in different function composition at the standard
temperature of 298.15 K. A very good numerical agreement has been obtained for the
prediction of the mixture densities. The analysis of structural and dynamic properties
showed that the molecular level of ternary mixtures is slightly affected by the
presence of MDEA and [gua][OTf] molar fractions. For MDEA–water interactions in
[gua][OTf] media, we found that MDEA prefers to be surrounded by water molecules
rather than by MDEA molecules even at a high MDEA molar fraction. While for
[gua][OTf]–water interaction in MDEA media, as [gua][OTf] molar fraction
increases, water molecules replace counterions in the coordination shell of both ions,
thus weakening their interaction. On the other hand, for MDEA– [gua][OTf]
interactions in water media, we have found that as the molar fraction of [gua][OTf]
increases, a sulfonate group from anion appears to have a stronger association by
making hydrogen bonding with MDEA molecules. The chemical process using ionic
liquids (ILs) as solvents is commonly limited by their high viscosity. Based on their
physical properties such as viscosities, these ternary solvents can be applied in natural
gas industry, such as removing carbon dioxide using aqueous MDEA and IL at high
pressure.

managing quality assurance and quality improvement. Quality frameworks include
quality assurance and quality improvement processes to ensure comprehensive
coverage of the factors affecting students’ experiences of learning. Aligning these
towards an e-learning design framework can benefit the administrators, designers,
developers, and students as well as improve the overall success and effectiveness of the
program. Over the past fifteen years a number of evaluation frameworks have been
developed for use in relation to e-learning. Most published frameworks have been
designed and validated in the context of developed countries. Thus, there is a need for
a quality framework in the context of developing countries, such as the Philippines.
While there are factors that are universal, there are also many factors that are
specific to developing countries. The categories where developing countries were
found to be facing much greater challenges were technological and contextual. The
technology category included infrastructure, costs, usability and appropriateness of
technology, while contextual challenges included organizational, and cultural or
societal challenges. This proposed quality framework in this study is focused on
contextual challenges that were identified in a previous study. In this study, the
Design and Development Research approach was used due to the use of qualitative
and quantitative methods. Qualitative method was used in the determination of
quality criteria and quantitative methods were used in the reliability and validity
tests.The main problem in this study was to design and develop a quality framework
that focuses on the contextual challenges in online distance education for higher
education institutions in the Philippines.

Abstract
Introduction: In 2011 Coronary Heart Disease (CHD) caused 57,864 or 13.73% of
total deaths in the Philippines according to WHO. The age adjusted death rate of
121.63/100,000 population ranks Philippines at number 79 in the world. Projected
deaths by CHD may reach 11.1 million globally by 2020. Hyperlipidemia is a
significant risk factor in the development of CHD. Any significant reduction in
mortality and/or disability from this disease will come from prevention and not cure.
Therefore increased awareness and reduction of risk factors maybe the best lines of
defense. Guyabano (Annona muricata Linn.) has been found to contain sterols and
triterpenoids, constituents which have been attributed lipid lowering properties. The
fruit pulp extract is lyophilized and the hypolipidemic property is explored through
comparison with atorvastatin (Lipitor).
Experimental:In this study the phytochemical constituents of the Guyabano fruitpulp extract was determined using standard tests. The hypolipidemic effect was
evaluated against atorvastatin (Lipitor) as standard drug using albino rats as test
animals. Hyperlipidemia was induced using an atherogenic diet of cholesterol. Three
concentrations of the fruit-pulp extract were used based on mg/kg body weight; 500,
1000 and 2,000. Results were obtained by comparison of total cholesterol (TC),

triglycerides (TG), Low density lipoprotein cholesterol (LDL-c), high density
lipoprotein cholesterol (HDL-c) and atherogenic index of plasma (AIP). After the tests
the test animals were sacrificed and histopathological evaluation of the liver, heart
and blood vessels of the atherogenic-diet fed albino rats were conducted.
Results and discussion: Bioassay findings show that the Guyabano fruit pulp can
control in a dose dependent manner the increase in TC, TG, LDL-c and AIP. It can
also decrease HDL-c caused by high fat and high cholesterol diet. Although results
were remarkable Guyabano fruit pulp did not prove to be superior to the
hypolipidemic effect produced by Atorvastatin. Histopathological analysis of the liver,
heart and blood vessels also revealed that the fruit pulp is effective in curtailing the
deposition of fats in the liver, heart and blood vessels which indicates potential ability
to prevent the recurrence of hyperlipidemia. Phytochemical screening confirmed the
presence of diverse constituents such as alkaloids, condensed tannin, polyphenols,
reducing sugars, fixed oils, unsaturated steroids, deoxy-sugars and flavonoids which
potentially might be responsible for the hypolipidemic effects.
Conclusion: Although atorvastatin proved to be superior in lowering TC, TG, LDL-c
and AIP and decreasing HDL-c the lyophilized fruit pulp of Guyabano showed a
significant lipid-lowering activity which increased as the dose is increased. It is
recommended that higher doses be used as the lyophilized fruit pulp extract is
relatively safe. The use of Guyabano however is suggested to be taken as a
supplement to the diet as the fruit is easily available in the Philippines. Guyabano to
some extent is effective in preventing the deposition of fats in the liver, heart and
blood vessels. A follow up study should be done wherein the induction of
hyperlipidemia is prolonged to thoroughly establish the hypolipidemic property of the
fruit. Further studies to investigate the possible mechanisms of action of the
hypolipidemic property are hereby recommended.

saman empty pods (SSEP) using Pleurotus ostreatus in a solid state fermentation
(SSF) for a period of eight (8) weeks. The fungus was able to improve the protein
content significantly (P < 0.05) above the control samples and protein enhancement
was highest in SSEP (23.86%), whereas SSWP recorded (13.90%). The crude fibre
significantly reduced (P < 0.05) in both substrates fermented, with SSEP recording
the highest of 24.37% and SSWP 18.36%. The ash content improved significantly
(P<0.05) with SSWP recording 41.42% and SSEP 22.95% at the end of the
fermentation period for 8weeks. The tannin levels in SSWP reduced by 58.54% and
50.72 % in SSEP. The study demonstrated that SSF of these agro wastes with P.
ostreatus increased the level of limiting nutrients e.g. proteins and minerals while at
the same time decreasing the fibre levels to enhance their digestibility for
monogastrics and ruminants.

ABSTRACT
This paper examined the Knowledge and Accessibility among academics on Online
Databases Subscribed to by University Libraries in Katsina State. Objectives of the
study were to find out the extent of academics knowledge about the online subscribed
databases, access points of online subscribed databases by academics and how
academics search and obtains downloads from online subscribed databases in the
university libraries in Katsina state. Survey research method was used and the
instrument used for data collection was questionnaire. Ninety nine (99) copies of
questionnaire were distributed to respondents in which a total of eighty five (85)
copies were duly completed and found usable. Responses were analyzed using
descriptive statistics. The findings revealed that most academics were aware of the
online databases subscribed, majority of the academics access online databases in
their Offices and mostly search by themselves. It is therefore, recommended that
management of the libraries should introduce user education and training
opportunities aimed at improving the accessibility of online subscribed databases
among academics in the university libraries in Katsina state.
Key words: Knowledge, Accessibility, Online databases, Academics, University
libraries.
